摘要： Before detecting a mechanical angular absolute position θabs of a rotating shaft (4) within one turn using a two-pole absolute value encoder (2) and a multi-pole absolute value encoder (3) having Pp (Pp: an integer of 3 or more) pole pairs, the rotating shaft (4) is rotated to measure a temporary absolute value θelt of the multi-pole absolute value encoder (3) in relation to each absolute value θt of the two-pole absolute value encoder (2), and a temporary pole-pair number (Nx) for a multi-pole magnet is assigned to each absolute value θt. In actual detecting, an absolute value θti of the two-pole absolute value encoder and an absolute value θelr of the multi-pole absolute value encoder are measured, the temporary pole-pair number (Nx) assigned to the absolute value θti is corrected on the basis of an absolute value θelti of the multi-pole absolute value encoder assigned to the absolute value θti and the measured absolute value θelr, thus calculating a pole-pair number (Nr). The absolute position θabs is calculated using an expression of (Nr×θelp+θelr)/Pp with a mechanical angle θelp corresponding to an electrical angle of one period of an output signal of the multi-pole absolute value encoder.

摘要： A motor encoder is mounted on a motor shaft of a geared motor 1, and the origin position is detected by using a Z-phase signal. An absolute value encoder with a precision that allows the number of motor rotations to be determined is mounted on an output shaft 4 of a reduction gear, and the absolute rotational position thereof is detected. When the first Z-phase signal generated in conjunction with the rotation of the motor shaft 2a is obtained at startup and at other times, the mechanical starting point at which the motor shaft and output shaft are both positioned at the origin can be calculated based on the absolute rotational position of the reduction-gear output shaft obtained from the output-side absolute value encoder. Since the mechanical starting point is obtained by rotating the motor shaft a single rotation at most, the time required to calculate the mechanical starting point is short in comparison with conventional examples, and extraneous rotational movements can be avoided.

摘要： A DC motor of a galvanometer-type scanner has four poles, and compared to a conventional DC motor with a bipolar construction, the armature inductance L can be reduced to half or less for a case where the external diameter of the rotor and the induced voltage constant KE are the same. Since KE/L, which is the index for the rise of torque of the motor, is increased by a factor of two or more, the responsiveness of the motor can be improved without increasing the exciting current of the winding. Accordingly, it is possible to provide a galvanometer-type scanner that can set minute angles of around one degree within several hundred microseconds.

摘要： Magnetic poles are provided continuously with a pitch .lambda. on the peripheral portion of a drum rotated in accordance with a movement of a moving body. A magnetic sensor is provided in opposition to these poles. The sensor is formed of two magnetoresistive element pairs which are spaced from each other at .lambda./6, and the two elements in each pair are arranged in positions spaced from each other at .lambda./2. The two elements in each pair are connected in series to form a bridge circuit. The signals obtained from the nodes of the series-connected elements in the two element pairs are differentially amplified so that third harmonic wave components are eliminated, and a signal having no distortion and representative of the position or speed of the moving body can be obtained.

摘要： A device for detecting a load torque using angle detectors fitted with a certain spacing on a shaft which is rotated by a drive source and on the basis of a relative angular difference of angles detected by the angle detectors. The device includes two rotary drums or discs fitted with a certain spacing on the drive side and load side of the shaft, with a plurality of magnetic poles for generating magnetic signals being formed on the surface thereof, and a magnetic sensor disposed to confront the surface of the rotary drums or discs, with magnetic resistance effect elements which vary in internal resistance in response to the magnetism of the magnetic poles being provided thereon. The amount of torsion created by the load on the load side of the rotary shaft is measured as a phase difference of outputs of the magnetic sensor, and the torque is detected in terms of the angular difference between the magnetic drums or discs. The device is operative to detect a torque in both storage and rotation, and capable of detection within a period of magnetic signal, whereby high-accuracy, high-resolution torque detection is made possible.

摘要： A magnetic position detector having a rotary magnetic recording medium which is movable with a movable body the position of which is to be detected. The rotary magnetic recording medium is divided into plural channels, each of which includes two tracks. A magnetic sensor is disposed to face the magnetic recording medium with a predetermined air gap therebetween and includes two sets of magnetoresistive elements spaced by a predetermined distance for each channel. Each set of magnetoresistive elements includes two elements wherein the first elements of the two sets face one of the tracks of a channel and the second elements of the other of the two sets faces the other track and the first and second elements of the two sets are formed as one body with adjacent ends of the first and second elements being coupled with each other. The coupled adjacent ends are connected to either one of first terminals for deriving output voltages from the magnetoresistive elements or to second terminals for supplying the magnetoresistive elements with source voltage. The non-adjacent ends of the first and second elements which are opposite to the coupled ends are connected to the other of the first and second terminals. In this manner, the sensor can be made small in size and the resistivity against noise is enhanced.

A free-running hardware timer and a soft-timer on a program controlled by an instruction execution time of a microcomputer are arranged so that ON-time data and OFF-time data of the pulse width modulation signal are selectively set in one and the other of the hardware and soft-timers in dependence on values of the ON and OFF times, respectively. The ON and OFF states of the pulse width modulation signal are changed when the contents of the hardware and soft-timers reach predetermined values so as to control the pulse width thereof.
